| 英文摘要 | In wireless transmission, H.264/AVC compressed video stream shows poorer image reconstruction quality due to the data losing, so this paper presents a spatial error concealment algorithm based on adaptive edge thresholds and directional weights. This algorithm uses Sobel gradient operator in image edge detection to detect the edge of adjacent macroblocks. Then it sets adaptively gradient threshold according to the specific information of adjacent macroblock in the damaged macroblock. Finally, it makes the direction weighted interpolation for the damaged macroblock implement the image reconstruction. Experiments show that the algorithm is simple and practical. It not only retains the advantages of the weighted average algorithm and conceals the errors of the images with different edge information intensities. The Peak Signal to Noise Ratio of the algorithm has improved 0.2-3.8 db as compared to that of the Multi-Directional Interpolation algorithm in different probability events of data losing for Real-time Transport Protocol (RTP). This algorithm improves the quality of image restoration and has a higher application value. 2016, Chinese Academy of Sciences. All right reserved. |
